Distributed Feedback Lasers
920 nm - 1100 nm
nanoplus Distributed Feedback Lasers (DFB) are specifically designed for high-precisiongas detection using tunable diode laser absorption spectroscopy (TDLAS). Our devices
operate reliably in more than 50,000 installations worldwide. For more than 20 years
nanoplus has set the standard for DFB laser technology and is the only manufacturer
routinely providing DFB lasers at any wavelength.

Any custom wavelength is possible: You tell
us what you need and we deliver it. With ourpatented DFB technology we design any
wavelength between 760 nm and 14 μm.

Overgrowth-free DFB device processing

Our excellent spectral purity is characterized
by a large side mode suppression ratio(SMSR) of > 35 dB, giving your system a lowsignal to noise ratio against crossinterference.

A narrow linewidth below 3 MHz guarantees ultra-precise scanning of the absorption linefeature. The high output power of several mW yields a stronger signal and increases yourmeasurement precision.
Fast and wide wavelengthtuning is required for in situ
systems. Most customers use ascan rate of 10 kHz and benefit
from our very large tuning
coefficient.

”Do not change your ideas, let us deliver
the laser that fits your application.”

We offer various packaging options, e.g. several
free space housings including TEC and NTC, fiber coupling,
collimation and custom designs. What do you require?
If you require custom specifications, pleasecontact us. Nearly 80 % of our devices are moreor less customer-specific. As nanoplus is a fully
vertically integrated company, we control theentire process chain from design to packaging.
Both nanoplus production facilities are based in Germany.
To guarantee consistent product quality we apply a strict
and ISO certified quality management system at all levels.
Our sales and R&D teams have long-standing experience in developing lasers.
They will advise you in your design and realization phase as well as after-sales:
We make market leaders!
